                Prefix searches with a type followed by a colon (e.g.
                <code>fn:</code>) to restrict the search to a given type.
            </p>
            <p>
                Accepted types are: <code>fn</code>, <code>mod</code>,
                <code>struct</code>, <code>enum</code>,
                <code>trait</code>, <code>typedef</code> (or

            <p>
                Search functions by type signature (e.g.
